Critial Velocities for Fuel in Pipes

Critial Velocities for Fuel in Pipes

Critial Velocities for Fuel in Pipes

(OP)
Hello,

I would like to know whether there is a limit to what velocity Diesel fuel can go (critical velocity) in a pipe to prevent static build-up (neglecting pressure loss considerations).

Thanks,
JP

RE: Critial Velocities for Fuel in Pipes

I doubt the velocity is a critical factor. Amoco did testing and got patent(s) on equipment to prevent static discharge at tank truck/barge loading racks (diesel and gasoline) ; as I remember veloccity was not a factor.

RE: Critial Velocities for Fuel in Pipes

The British standard BS PD CLC/TR 50404:2003 prescribes pipe flow velocity limits for hazardous fluids  

RE: Critial Velocities for Fuel in Pipes

10 ft/s (3 m/s) is a common rule to limit excess splashing/atomization within closed process equipment (hydrocarbons).

Excellent. Thank you.  

RE: Critial Velocities for Fuel in Pipes

but that is not an inside-pipe velocity limit.
